To all whom it may concern: l 4 Be it knownthat I, EMIL EINFELDT, of Davenport, county of "Scott, and State of Iowa,

have invented a'new and useful Improvement in Axles, of which the following is ja specification. l y

This invention relates to the construction .of axles; and the invention comprehen'ds a composite axle in which the main body portion is of wood and the bearing-spindles of metal and formed from sections of flanged metallic bars, the anges of which are shaped to present rounded bearing-surfaces or\wheel spindles. y

The invention resides in 'the .manner of uniting the parts, the end of the wooden body 4 I cordance with my invention. Fig. 2 is a top plan view of the same. Fig. 3 is avertical transverse section on the line c aof Fig. 1. Fig. 4 is a perspective view of one end ofthe body portion of the axle with the hanged sec- Referring to the drawings, my improved axle consists of a Vmain body portion A,.of

wood, and wheel-'spindles B, of metal, which spindles are firmly fixed to the ends of the 4wooden body portion. The wheel-spindles are each formed from a short length or section of flanged bar, preferably commercial I-beam, comprising a central web b and longitudinal vflanges b and b2, projecting laterally I from kthe up er and lower edges of the web.

The flanges or a portion of their length are curved inward toward each other, forming a rounded bearing-spindle C, while for the re-y 4 mainder of theirlength; they extend straight and'present on opposite sides of the web open channels. Y The end of vthe wooden body `portion of the axle is formed with a central open slot a, which embraces the web of the flanged section, and ythe slotted end of the wooden bar is formed and shaped so that it will snugly and completely fill the open channelsv be'- tween the flanges of the metallic section', the upperV and lower edges of the body A extending along the inner faces of the flanges and the inner lwalls of the slot in said body ex tending at the sides of the web b, as clearly shown in Fig. 8.

The parts are held firmly and fixedly together by means of fastening-bolts D, in the present instance four in number, extending through the slotted end of the wooden body and through the web b ofthe flanged section. The flat flanges of the end section of the axleby bearing, respectively, against the up- -per and lower edges of the wooden body porltion afford a strong and effective su port for the spindles andk prevent the same om sagging or shifting out of a true osition in line Instead of employing an I-beam section for the wheel-spindles they may be formed from a section of flanged bar of "IL form in cross section, as shown in Fig. 5. This would necessitateno change in the form of v the slotted end of the wooden body portion of the axle or the manner of connecting the same with the flanged sections. struction the upper flange at one side of the metallic section willbear on the up er edge of the axle-body at one side, while t e lower flange at the opposite side of the metallic section will bear against the under side of the `with the longitudinal center o the axle-body. l

axle-body, with the result that the flanged section will be given firm and rigid support and will be` prevented, asin the first instance described,frorn being shifted vout of position.

- The employment of my invention in con` nection with the manufacture of 'axles will enable a'wheel-bearing of large diameter to l be obtained with a minimum amount of Inaterial, a saving f being effected both in the length of the wooden body of the axle and in its thickness. l.

`I-Iaving thus described invention, what,v i

I claim is-` y 1.. In an axle, thecombination with a main body portion, of' an end section provided with longitudinal flanges and a connecting-web, and shaped to'constitute a wheel-spindle, the end of theb'ody portion being seated against and secured to the web of theend-section, with the viianges of the latter bearing along' the edges of the body portion.

2. An axle comprising a .main

IOO

tion having its end slotted, and an end section having longitudinal flanges and a connecting-web, the said web being seated and secured in theslot in the body portion, with the ends of the latter itting between the longitudinal lianges of the end section.

3. In an aXle and in combination with an end section shaped at its extremity to form a wheel-spindle and formed in its sides with open longitudinal channels, a main body portion having its ends shaped to it in said channels, and means for fastening said parts rigidly together.
